I sometimes post comments on other people's blogs, then forget whose blog I've commented on, and on what topic. It would be nice to be able to go back and see if anyone is replying to my comments. Now there's a tool to do that.
www.CoComment.com has a free, easy service that captures your comments as you make them. Then it provides a personalized web page that shows all of the comments you made, and other comments made after yours.
If you try it (or you have an alternative way of accomplishing this), let me know.
